在假设拒绝区间没确定的情况下,对给定的样本,在H0假设下,我们选择一个拒绝区间,使得拒绝这个样本的概率(也就是一类错的概率)最小,这个概率叫做p-value(这就是为何之前的答案不妥,p-value是个最小值,只不过由于某人答案里拒绝区间只有一种,所以最小值就是唯一的值,那个答案没错,但定义不全面)。 费舍尔这时候跟...
The Log2 fold-change (L2FC) is an estimate of the log2 ratio of expression in a cluster to that in all other cells. A value of 1.0 indicates 2-fold greater expression in the cluster of interest. The p-value is a measure of the statistical significance of the expression difference and ...

Thanks to the graph, we were able to determine that our results are statistically significant at the 0.05 level without using a P value. However, when you use the numeric output produced bystatistical software, you’ll need to compare the P value to your significance level to make this deter...
The p-value of the test statistic is a way of saying how extreme that statistic is for our sample data. The smaller the p-value, the more unlikely the observed sample. Difference Between P-Value and Alpha To determine if an observed outcome is statistically significant, we compare the valu...
difference )，是一个统计学名词。它是统计学（Statistics ）上对数据差异性的评价。通常情况下，实验结果达到005水平或001水平，才可以说数据之间具备了差异显著或是极显著。3、P值（P value）就是当原假设为真时所得到的样本观察结果或更极端结果出现的概率。P值越小，表明结果越显著。但是检验的结果...
The lower the p-value, the greater the statistical significance of the observed difference. A p-value of 0.05 or lower is generally considered statistically significant. P-value can serve as an alternative to—or in addition to—preselected confidence levels for hypothesis testing. ...
The p-value is a measure of the statistical significance of the expression difference and is based on anegative binomial test. The p-value reported here has been adjusted for multiple testing via theBenjamini-Hochberg procedure. In this table you can click on a column to sort by that value....
